Fitness age diffs men and women?

There are no tips for me to improve.

Did you try tapping and reading the Help in the top right corner? If still in doubts, there is some info available also on Garmin's support website: What Does Fitness Age Mean in Garmin Connect? | Garmin Customer Support

Edit: Although the screen tells you already reached the achievable fitness age, I think it can drop even more. At least I saw my FA already dropping below the achievable level too. You simply have to improve the four factors listed on the screen, to get younger

... and also - older devices do not use the same method for the Fitness age. Older devices base the FA purely on VO₂max, while newer devices on those four factors and no VO₂max. So it is quite well possible your friends have the FA based on VO₂max - check out the list of devices on the page I linked in my previous post.

The new fitness age function can only set your age ~10 years younger than you are so your friends got the old fitness age function. "Everyone" had 20 as their fitness age with the old function.

Yes, 10 years younger minimally, not sure whether more is possible. I've been already 10 years down (with the new method), despite that the FA page showing that the achievable age is 2 years higher than that. So the message about the achievable age is not to be taken seriously.

I've only seen 9.5 years but I guessed it would go to at least 10 years younger. We will see if anyone can break that :-)

Why not just lower your age to be 10 years lower? Set your age to 35 instead of 45.

If you’re fit as you think, it should be lower right?

Then the whole point of fitness age is missed. There are a number of factors that are taken into account to calculate the fitness age. The fitness age is not used for anything AFAIK. It is just another evaluation of your physical state that you can use in any way you like.

If you lower the real age then the fitness age will be even lower.

I’d hope they’re measuring a users data against avgs for an age/gender profile, which will be higher for an 18 vs a 60.

The Insights are using age groups.

I don't know if the performance and health values need to use the age that much. VO2 max, heart rate and more are not using age. They are absolute values. Calorie burn is affected by age in real life, but it Garmin adjusts for that is unknown.

BTW, I have to disappoint some of you - Garmin's Fitness Age algorithm cannot generate an accurate prediction for individuals older than 90 (and younger than 20, too).
